Hey all,
Here's a pretty cool macro DSLR effect I discovered the other day. FINALLY a use for 4K video resolution!
All you have to do when in video mode is select 4k (3840 × 2160) and zoom in 4x. When close to a subject tap to focus as usual and you may be shocked that the image suddenly has crazy depth of field but still remains sharp.
The reason? The camera module has an aperture of f/2.2 which is great, but that's not the real clincher. 4K UHD has 8,294,400 pixels in a frame. Just to give you an idea 1080p is only 2,073,600 pixels. So basically, when you zoom in 4x, your image still looks great. No other phone camera can do this in 2013.
Big deal, SO WHAT? you may be thinking. Well the results CLEARLY speak for themselves..
Happy shooting!

Are you saying that if you record in 1080p mode and framed the shot exactly the same, that the depth of field would not be the same? I'm confused?
I understand the merits of 4K recording, but I don't see how the depth of field would be affected.
WOW! Cant believe all that comes from the small lens sensor of Note 3

I probably should have explained this better but you can't really frame the same shot in 1080p because you'd be way too close to the subject for the camera to even attempt to focus on it. 4k allows much more flexibility for macro shots.
And do you have a 4K display to see this awesomeness?
Otherwise you're just watching it at 1080p lol.

Now I'm curious how 4K video zoomed in 4x downscaled to 1080p compares to 1080p video zoomed in 4x. I wonder if Samsung is using software zooming to enlarge the video image or cropping the sensor to achieve the field of view. If it's software zoom then there's obviously going to be a loss in quality. But if it's simply cropping the sensor there should be no difference. And it fact it'd be a waste of time and memory space to shoot in 4k zoomed to 4x and then having to downscale it to 1080p afterwards. That would add unnecessary steps for editing. Also, in 1080p mode you have access to the software video stabilization while in 4k mode you don't.
it's not about the resolution lol. think putting on different DSLR lenses for your phone.
great find, OP! will be trying this soon
4k works with approx 50% more colours than normal 1080p. Even if you dont have a tv to warch it in full res, a 4k clip will look and FEEL rather different than everything else.
The clip in the above link is done with a little bit of postproduction. Indeed its impressing and there is more to be discovered.
_madness haven't any rest, only swet_

lol, it's not about the resolution. it's kinda like being able to use different lenses for your note 3.
great find, OP. thanks!

Cropping a sensor of say a 35mm legs by 1.6 doesn't give you a 56mm zoom perspective. You're still getting a relatively wide angle shot but simply cropped.

I understand that. However, in this instance is 1080p mode on the Note 3 simply cropping the sensor to begin with? My question in relation to the OP is if you shoot at 4K mode, zoom in a 4X, is the phone simply cropping the sensor 4x to give you a lossless zoom? Or it is using some type of software pixel binning to give you the zoomed in view? Or perhaps a combination of both.
And how does that compare to shooting in 1080p mode with the 4x zoom?
I took a few sample videos sitting at my desk and to my naked eye viewing both videos on the Note 3's screen, there is 0 difference between shooting at 4K resolution with a 4x zoom and shooting at 1080p at 4x zoom other than the file size. The field of view is identical. I'm looking to see if there's any advantage at the end of the day if I want to end up with a 1080p file as the end product. Is there any advantage to shooting the same field of view at 4K and downscaling?
The 4x zoom when shooting at 4K did not give me a distance advantage versus shooting 1080p at 4x zoom. The phone remained at the same distance as my subject when framing the shot with the same field of view. So for macro video shots, I do not appear to have any advantage when shooting at 4K.
Epic and very well done video!

I think what he's saying is that no matter of 1080p or 4k, distance and senzor pixels are the same, therefore theoretically you shouldn't necessarily have to do 4k to do such zooming. Question is: in effect does zooming in 1080p still record lossless as far as the sensor goes (13mil pixels), or zooming in 1080p only zooms into the 1080p capture (magnifies the 2mil pixels).

I just assumed that zooming in ALWAYS "magnified" the pixels so you'd naturally just get sharper detail with the 4k mode. I now understand my error with the field of view though (I tried it out myself too)
I guess the main thing to take home is the amount of detail you're getting from this phone's sensor.
Appears to be two tradeoffs in the camera...
1) cannot use video stabilization at the same time as tracking AF
2) you lose a lot of the advanced capabilities in 1080p 60fps.
Which of these are worth the loss in people's opinion?
You only lose digital stabilization* during 60 FPS video filming. The hardware OIS remains active.
There are multiple downsides to filming consistently in 60fps, low light suffers and you lose a couple other video features in order to gain smoother motion.
For day to day video filming, 1080p 30fps is the ideal with the least amount of compromises, of course if you're filming a fast moving subject, flip the switch to 60fps.

It's a phone, I don't record videos like a professional.

Neither. Video stabilization is usually pretty annoying. The 60fps loss is a little bummer but for most activities 60FPS does little but take up more space anyways.
Also there is a loss of detail per frame in 60FPS. The S6 does 17Mbps @30fps but 28Mbps @60fps which has 2 times the frames. So the individual frame data is capped at 14Mbps minus audio.
Has anybody noticed how terrible the video recording performance is on this phone? Even in fairly well lit conditions there's so much smoothing going on it makes the overall video look absolutely terrible.
Is there a way to turn this smoothing off? I have been using GCam purely for recording videos and the quality is a lot better (doesn't have this smoothing effect) but the app itself isn't perfect and crashes fairly regularly. Any suggestions/known fixes welcome
I have my video settings set to 4k 60fps.
TIA.
I noticed this too.
Even on 60FPS it is not as smooth as I was hoping - my eyes actually hurt when I watch videos with moving objects.
Still objects are very, very good, especially with 5X optical zoom.
I think this is something to do with steadiness not with FPS.
Electronic Image Stabilization, the function that is digitally trying to improve stabilization for shaky videos is also happening in steady videos. I have been shooting a really steady video taking an interview and there were frames jumping and moving as trying to steady the video shot. I have the Exynos version. What is this Samsung. Footage is ruined. You cant fix random frame jumping/rotating in small angles video even in post processing afterwards. Please, feel free to state your experience too. I think that Samsung over-corrects video, even the non shaky ones. I wish there was an ON/OFF switch at least in the VIDEO PRO MODE.
So far liking the new 7p, havent seen any crazy battery drain or anything yet.
Camera can shoot 30x pics but only 20x video... any idea why? Tried changing settings (1080p, 30fps) to no avail.
Wonder why we cant shoot HDR in 60fps either...
Can the 6p do these?
Thanks
Likely due to lack of light and/or processing power. The 7 Pro uses the telephoto lens that can do 5x and 10x with a 1:1 crop. Everything between or beyond those steps get processed with data from the main sensor and the new Super Resolution AI. Considering it can do 30x for a single frame. Mediocre 20x for 30/60fps is seems fine for video.
I am also miffed about not having HDR at 60fps especially since we can now do full zoom on FHD/UHD unlike the 6 Pro getting locked out of 60fps for UHD 4x zoom.
